Association between insulin resistance and breast carcinoma: a systematic review and meta-analysis.

Objective: This study was undertaken to evaluate the association between components defining insulin resistance and breast cancer in women.

Study Design: We conducted a systematic review of four databases (PubMed-Medline, EMBASE, Web of Science, and Scopus) for observational studies evaluating components defining insulin resistance in women with and without breast cancer. A meta-analysis of the association between insulin resistance components and breast cancer was performed using random effects models.
